RENEWABLE CHECK-VALVE.

SPECIFICATION forming part of Letters Patent No. 485,745, dated November8, 1892.

Application filed April 14. 1892'. Serial No. 429,115. (No model.)

To a whom, it may concern:

Be it known that I, WALTER S. LovELAND, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inRenewable Check- Valves, of which the following is a full, clear, andexact specification.

The invention relates to the class of straightway check-valves having aremovable disk, the object being to so construct such a valve that it ischeap, light, strong, and readily assembled, from which both the diskand seat can be readily and quickly removed for renewing, repairing, andcleaning.

Referring to the accompanying drawings, Figure 1 is a plan of the valvewith the cap removed. Fig. 2 is a longitudinal vertical section, andFig. 3 is a transverse vertical section of the same.

In the views, 1 indicates the body of the valve, which is cast to shape,of brass, bronze, iron, or other suitable material, with pipe ends 2 formaking the connections, and cap end 3, which maybe opened forremovingorinspecting the disk or seat. These ends are usually threaded,as shown, but may, of course, be belied or flanged, if desired, forother forms of connections.

In making the valve, grooves or mortises 4 are cut in the walls uponeach side from top to bottom of the interior chamber adjacent to theport 5. These grooves usually incline from the top to the bottom and arepreferably milled with a beveled or V-shaped cutter, the wall of thebody ordinarily being slightly thicker to accommodate the grooves. Anannular seat or ring 6, of brass, babbitt, asbestus, composition, or anyother suitable material, with beveled edges to fit the grooves, isloosely placed in the interior, so as to lie against the face around thepart5,and upon this, with its lower edge formed to fit the top of theseat and with its side edges beveled to ble and will fit tightly andclosely against the front face of the loose seat that is in front of theport.

When the valve has been connected with pipes in position, the seat isdropped into the interior, so as to lie around the port with its sideedges in the grooves and its lower edge resting on the bottom of thebody. The plate bearing the swinging arm and disk is then placed uponthe seat and when the cap is screwed to place it holds the plate down,so that the seat is also firmly held in position. As there are noopenings in the body except for the connections and cap, the walls maybe made light and still be strong. The grooves are easily milled, theseats are cheaply formed, and the plates accurately made and readilyplaced in position to hold the seats firmly in place, while the .capholds the plate in place, so that the disk will fit closely and tightlyagainst the seats, always in the same position, without special accuratefitting. When the cap is removed, the disk and seat can be lifted outfor renewing, repairing, or cleaning.

I claim as my invention- A valve consisting of a body having grooves inthe interior extending from top to bottom of the opposite walls, anannular seat loosely inserted in the grooves, a plate loosely insertedin the same grooves and resting upon the annular seat, ears projectingfrom the plate, an arm pivoted to the ears, a disk supported by the arm,and a cap for holding the plate in position, substantially as specified.
